    Spacing for rivets in tail? (aluminum)

    "There is also guidance on rivet spacing in the much-beloved FAA AC 43.13 "acceptable methods and practices" book. As a GENERAL RULE, with AIRCRAFT rivets, used in SHEET METAL semi-monocoque construction, spacing of 4D (4 times the rivet diameter between hole centers) is the closest you will...

    Spacing for rivets in tail? (aluminum)

    "discrete joints like these really must be analyzed and engineered on a case-by-case basis, considering all the loads being reacted at them and the resulting strength requirements. Special attention must be applied to joints along control surface leading edges that react torsion into and out of...

    Spacing for rivets in tail? (aluminum)

    Thanks for all the ideas, especially the articles by Chris Heintz "Heintz Design College." Everything I find has rivets generally with spacing 1/2 inch to one inch; occasionally more. Examples shown:

    Metal thickness for gussets on ultralight aluminum-frame tail?

    OK, how does one verify that an "existing design" properly computed Span, area, pressure loading, configuration of the structural members? Who computed structural analysis of the Backyard Flyer, or the Legal Eagle? I am not saying none was done, but I can't find any report. In fact I can't...

    Metal thickness for gussets on ultralight aluminum-frame tail?

    What is a good thickness for gussets on a tail made with aluminum tubes (say 5/8 to 1 inch tubes)? The Legal Eagle uses 0.030 inch in 6061 T6; other gussets I see are more.

    Spacing for rivets in tail? (aluminum)

    What is a good spacing for rivets in gussets on a tail made with aluminum tubes (say 5/8 to 1 inch tubes)? Belite says they use 'commercial' rivets not aviation rivets. What is the difference?

    What is the Best Airfoil for a USA Part 103 Ultralight?

    airfoiltools.com will provide numerical coordinates, drawings up to full size, and aerodynamic data including polars. See for example http://airfoiltools.com/airfoil/details?airfoil=naca4412-il The polars are computed not measured so although they look impressively accurate, actual...

    Painting exposed aluminum tubes on an ultralight - which paint?

    Purely for appearance I am thinking of painting exposed aluminum tubes on a ultralight a pale golden yellow. To save weight I suppose spraying would be best. What paint would be best? Will any paint stick to exterior aluminum for long? Do the "paint plus primer in one coat" products add any...

    Very good. Also: Falcons of France by Charles Nordhoff. American WW I pilot and later a popular novelist. Many Nevil Shute books have aviation, but not On the Beach. The Rainbow and the Rose made my wife want to learn to fly a Gypsy Moth. What other flying book does that...

    Technical History of the 1909 Demoiselle

    Thanks! I did not know about the yahoo group. The pdf file is a miscellaneous collection from several sources. The title "Demoseille" is misspelled. Pages 2 and 3 are from a Clement Bayard booklet, for the Demoiselle, Santos Dumont No. 21 or 22, from late 1909. Yes the airplane (less engine)...
